To all whom it may concern:

Be it known that I, ALFRED TURToN, a subject of the King of Great Britain, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Plasterers" Running-Molds, of which the specification.

'l\ y invention relates to improvements in plasterers running-molds such as are used in forming plaster cornices and the like, and comprises a mold which may be used not only on cornices of considerable length but on short breaks, &c., and with which a cornice may be formed clear up to acorner, thereby avoiding the necessity of finishing in corners by handwork or the use of preformed cornices.

My improved running-mold is adapted for the making of cornices, panel-molds, impostmolds, beam-molds, skirting-molds, &c., of any given dimensions and of any desired design.

.In the ordinary practice of formingcornices and the like plasterers commonly use a sliding tool termed a running-mold, having a shaping edge corresponding in contour to the sectional contour of the cornice to be produced, said tool being run back and forth over suitable temporary guides attached to the wall or ceiling for the purpose, and thereby shaping plaster applied at the place where the cornice is to be formed while the plaster is still plastic and. setting. It is well known, however, that as ordinarily constructed these running-molds are incapable of extending the cornice into a corner, nor can such molds be used on short breaks, so that in corners and on short breaks the cornice must be worked in by hand or else premolded cornice-blocks following is a must be cut and mitered, an operation en tailing much waste and occupying much time, and then planted in position.

The objects of my invention are to avoid the necessity of finishing cornices by hand or of cutting and planting premolded cornices to permit the molding in situ of cornices and the like clear into the corners, to permit the formation of the cornices of short breaks, &c. by the running-mold, and to provide a running-mold fulfilling the above requirements and which is strong, simple, inexpensive, and easy to operate.

I will now proceed to describe my invention with reference to the accompanying drawings, illustrating one form of cornicemold embodying my invention, and will then point out the novel features in claims.

In the'said drawings, Figure 1 shows a top or plan view of the improved running-mold and indicates in full and dotted lines two alternative positions of the hinged member of the guide or slipper. Fig. 2 shows a side View of the running-mold, the hinged member of the slipper being turned back. Fig. 3 shows an elevation of the running1nold with the hinged member of the slipper at right angles with the fixed member thereof, the view being taken looking directly at the edge of the forming-tool, the slipper being therefore at an angle with respect to the plane of view. Fig. 4 is a detail section showing the hingejoint. I

My improved running-mold comprises a slipper or base formed in two sections 1 and 2, hinged together at 3, a templet or formingtool 4, cut to the contour which will produce a cornice or the like of the desired contour, a support or backing 5 for this templet usually braced by means of an angular brace 6, which also forms a handle, and means for fastening the hinged section 2 of the slipper in position as, for example, a brace-rod 7. A handle 8 is usually provided as well for convenience in handling the mold. The templet 4 extends across the axis of the hinge-joint, as shown. Means are provided for holding the hinged member 2 of the slipper in the position to which it is adjusted, such means in the instance shown being a brace 7, pivoted to the section 1 of the slipper and adaptedto be pivoted at the other end to the part 2, either at point '10 (in which case the two members of the slipper are at right angles) or at point 11 (in which case the two members of the slipper are in line) by means of a screw 12, adapted 9 to be inserted into holes at points 10 and 11;

but any other suitable adjusting device may be employed instead.

In ordinary operation-that is to say, when forming a cornice or the like on an unbroken wall of considerable length the hinged member 2 is in line with member 1, as indicated in dotted lines in Fig. 1, being secured in such position'by the brace 7. The mold is moved back and forth along the wall and upon the temporary guides provided for the purpose on the wall or ceiling, shaping the plastic stucco, cement, composition, or other material from which the cornice is formed until a hard and smooth finish is obtained.

One member of the slipper being in advance of the templet in whichever direction the mold is moved, the mold is well guided, thus making it easy to produce a true regular cornice. The direction of advance is in the direction of the member 2, and when approaching a corner or break the member 2 is turned back and fastened in such position so that the templet may be run clear into the corner and then drawn out parallel to the second wall, the member 2 acting as a guide, thus forming a complete and perfect miter entirely by the action of the mold and without any handwork whatever. When working on very short breaks and the like, the member 2 of the slipper is retained in the rearward position, (in which position it is shown in full lines in Fig. 1,) the additional guiding action of this member 2 not being required; but when the length of the wall permits the member 2 is preferably in line with member 1, as the provision of a guide on both sides of the templet greatly facilitates the use of the mold.

Obviously templets of different contours may be applied to the mold, the latter being adapted to use templets of any desired contour, What I claim is i 1. In a running-mold of the class described, the combination with the slipper formed in two parts adapted to be arranged in line or at an angle with respect to each other, and means for holding said parts in the position to which they are adjusted, of a templet and means for securing the same to and supporting the same from the slipper, one part of the slipper being in advance and the other in rear of such templets when said parts of the slipper are in line.

2. In a running-mold of the class described, the combination with the slipper formed in two parts hinged together and adapted to be adjusted in line or at an angle with respect to each other, and means for holding said parts in the osition to which they are adjusted, of a temp et and means for securing the same to and supporting the same from one member of the slipper, one part of the slipper being in advance of and the other in rear of such templet when said parts of the slipper are in line.

3. A running-mold of the class described comprising a templet and means for supporting and guiding the same comprising two slipper members hinged together and held in the position to which they are adjusted by a brace, said brace arranged to hold said slipper membersin line with each other or at an angle with respect to each other, at will, one of said slipper members being in advance of, and the other in rear of, such templet when the parts of the slipper are in line.

In testimony whereof I afiiX my signature in the presence of two witnesses.
